Answer:
C
Step-by-step explanation:
Given that (x + 8) is a factor of f(x), then x = - 8 is a root and thus
f(- 8) = 0

Start off by finding the slope of the line with the formula
.
Substitute the values. ![\frac{1-3}{1-0}](https://tex.z-dn.net/?f=%5Cfrac%7B1-3%7D%7B1-0%7D)
Subtract. ![\frac{-2}{1}](https://tex.z-dn.net/?f=%5Cfrac%7B-2%7D%7B1%7D)
Simplify. ![-2](https://tex.z-dn.net/?f=-2)
is the slope of the line.
Now, use the point-slope formula to create an equation, where
is the slope and
is a known point on the line. ![y-y_1=m(x-x_1)](https://tex.z-dn.net/?f=y-y_1%3Dm%28x-x_1%29)
Substitute the values. ![y-3=-2(x-0)](https://tex.z-dn.net/?f=y-3%3D-2%28x-0%29)
Simplify. ![y-3=-2x](https://tex.z-dn.net/?f=y-3%3D-2x)
Move the
to create the final equation in slope-intercept form. ![\large\boxed{y=-2x+3}](https://tex.z-dn.net/?f=%5Clarge%5Cboxed%7By%3D-2x%2B3%7D)
Answer:
The total cost is $32.40
Step-by-step explanation:
9.91 x 4 = 39.64
25% of 39.64 is 9.91
39.64 - 9.91 = 29.73
6.75% of 39.64 is 2.67
29.73 + 2.67 = 32.40
Answer:
Range A = 386ft
Range B = 427ft
B has the larger range.
Explanation:
To find the range, find the difference between the minimum and maximum depths for each submarine. Remember that your answer will be positive.
Sub A:
-146ft - (-532ft) = 386 ft
Sub B:
-194ft - (-621ft) = 427 ft
Submarine B has a larger range.
Answer:
112
Step-by-step explanation:
Since the line is straight (180 degrees), you would subtract 68 from 180: 180-68=112. So f=112 degrees
